The Oklahoma seaside alder (Alnus maritima ssp. oklahomensis) is a shrub that grows almost exclusively in Johnston County. While individuals resprout vigorously from rootstocks, few seedlings have been observed in the wild. We surveyed 1,848 one-mete

Phylogenies are a ubiquitous visual representation of core concepts in evolutionary biology and it is important that students develop an ability to read and correctly interpret these diagrams. However, as with any representation of complex disciplina

PREMISE OF THE STUDY Bet-hedging strategies maximize long-term geometric fitness at the cost of reduced arithmetic fitness by offsetting different mortality risks. Heterocarpic systems accomplish bet-hedging through the production of two or more frui

Seed mortality due to low winter temperatures has been proposed as an explanation for the lack of seedling recruitment in natural populations of the rare riparian species Alnus maritima, but other factors such as the absence of essential root symbion

Effective conservation requires an understanding of the genetic interactions among populations and individuals of a species, particularly those with fragmented, isolated distributions. Alnus maritima (seaside alder) is a rare tree species with an ext

Small, isolated populations are prone to genetic drift and high levels of inbreeding that can threaten their long-term survival. Alnus maritima persists exclusively in three groups of small, highly disjunct, regional populations in the Delmarva Penin

We isolated and characterized 19 microsatellite loci from the endangered seaside alder, Alnus maritima. Loci were screened in 24 individuals of A. maritima and four individuals of its congener the hazel alder, A. serrulata. The number of alleles per

We conducted a population genetic analysis of the heterocarpic species Heterotheca subaxillaris (Asteraceae, camphorweed) to determine whether there are mating system and, consequently, genotypic differences between ray and disc achene pools that cor
